[Kernel-packages] [Bug 1292400] Re: task systemd-udevd:1906 blocked for more than 120 seconds.
This bug has been quiet for a while by the looks of it so just chipping in. I can confirm I witnessed this bug last week on an Ubuntu 14.04 x64 VM on a Windows Server 2012 R2 Hyper-V server with dynamic memory enabled on the guest. I suspect that dynamic memory (aka. memory hot- add/remove) may be related to this issue. If so, creating a VM with dynamic memory enabled and then running a workload that is memory intensive to ensure the Hyper-V server allocates more RAM to the VM may be beneficial. The tie-in with the balloon driver is interesting, and might suggest there's some level of interaction going on between these two components? Perhaps after dynamic memory adds more RAM to the system the balloon driver may trigger the issue due to no longer valid assumptions, or alternatively, the removal of memory from the system once it no longer needs it has a similar effect? It may also be useful for others to know that we initially detected this issue due to it causing a very high load average on the affected system which can be trivially detected by monitoring systems like Nagios. Note that while the load average is high, this doesn't correspond to any given process actually consuming substantial CPU resources, so you'll want to take a look at the dmesg output which will confirm if you're experiencing the issue via the blocked systemd-udevd and kworker processes. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1292400 Title: task systemd-udevd:1906 blocked for more than 120 seconds.

[Kernel-packages] [Bug 1345059] [NEW] linux-cloud-tools missing from precise
Public bug reported: The Trusty Tahir Hardware Enablement Stack for Ubuntu 12.04 is available and being aggressively promoted to existing Ubuntu 12.04 deployments running now End-of-Life Hardware Enablement Stacks. However, the linux- cloud-tools packages have not been made available to Precise users. This package was newly introduced in Trusty Tahir and contains cloud specific tooling associated with a given kernel version, separate from the general tools provided in the linux-tools packages. Right now, this package only contains Hyper-V specific daemons and utilities. The result of this is that on updating to the Trusty HWE the userspace hv-kvp-daemon Hyper-V daemon previously provided by the linux-tools packages is no longer present and will fail to start when the hv-kvp-daemon-init package attempts to do so: hv_kvp_daemon not available for kernel 3.13.0-30 This is in my view a very serious issue as it risks potentially breaking Hyper-V deployments of Ubuntu 12.04 which have either updated to the Trusty HWE or will be installed via the 12.04.05 installation media (the latter has yet to be released). From my brief look at the packaging situation the linux-cloud-tools packages depend on a newer version of sysv-rc than is currently available for 12.04, though, this is the only unmet dependency and I'm unsure if the newer sysv-rc is technically required or was just pinned against the release that Ubuntu 14.04 shipped with. ** Affects: linux-meta (Ubuntu) Importance: Undecided Status: New ** Package changed: hv-kvp-daemon-init (Ubuntu) = linux-meta (Ubuntu) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-meta in Ubuntu. https://bugs.launchpad.net/bugs/1345059 Title: linux-cloud-tools missing from precise Status in “linux-meta” package in Ubuntu: New Bug description: The Trusty Tahir Hardware Enablement Stack for Ubuntu 12.04 is available and being aggressively promoted to existing Ubuntu 12.04 deployments running now End-of-Life Hardware Enablement Stacks.
